New knuckle with unique "knuckle lock function" which can reduce majority of play of front suspension so as to improve car handling.

One small screws were planted into each knuckle to 'lock' its position on the king pin (i.e. knuckle lock function). The benefit of which is moving parts of front suspension is reduced from stock set up's three (knuckle, pin & ball) to currently two (pin & ball only).

This can substantially reduce play and provide better driving experience.
